# Great Graphs (1999/2000)

### Summary

Students will create a bar graph to demonstrate quantity.

• Quarter

### Coin Program(s)

• 50 State Quarters

### Objectives

Students will create a bar graph to demonstrate quantity.

• Math

• Art

• Kindergarten

### Class Time

Sessions: One
Session Length: 20-30 minutes
Total Length: 0-45 minutes

• Small groups

• Bar graph
• Record
• Data
• Sort
• Least
• Most

### Materials

• Plastic bags
• 10 copies of "Cool Quarters" coin sheet (page 16), laminated and cut
• "Great Graphs" worksheet, one per student
• Crayons

### Preparations

1. Make 10 copies of the "Cool Quarters" coin sheet (page 16). Laminate sheets and cut out coins. (A great idea for a parent volunteer!)
2. Prepare 6 bags with a mixture of the 2000 quarters (Massachusetts, Maryland, South Carolina, New Hampshire, and Virginia).  NOTE: Do not put more than 10 of any type into each bag.

### Worksheets and Files

Lesson plan, worksheet(s), and rubric (if any) at www.usmint.gov/kids/teachers/lessonPlans/246-251.pdf.

1. Focus on the objective by saying: "Today we are going to make a bar graph."
2. Ask the students to explain what a graph is.  Provide correct information, if necessary.
3. Tell the students that they will be collecting their "data," or information, using the bags of "quarters."
4. Distribute bags, along with the worksheet entitled "Great Graphs" (page 17).
5. Have students sort their quarters into groups based on state symbols (all Massachusetts coins in one pile, all Maryland coins in another pile, and so on).
6. After all the quarters have been sorted, have students begin with the Massachusetts group. Explain that they need to count how many are in the group and record the information by coloring in that many spaces on the graph.
7. Continue this procedure using the Maryland, South Carolina, New Hampshire, and Virginia quarters.
8. Assist students in using their graph to answer the three questions on the "Great Graphs" worksheet (page 17).

### Enrichments/Extensions

1. You can change the coins on the "Great Graphs" worksheet (page 17) by reducing the 1999 quarters (page 16) by 85% and gluing the 1999 quarters over the 2000 ones before making copies.
2. Make a large classroom graph to record how many of each quarter the class can collect over a certain time period—1 week, 2 weeks, etc.

Use the worksheets and class participation to assess whether the students have met the lesson objectives.
